Scratch -
its not a teachers job to make your education interesting? o....k....
So what IS my job? please educate me i woudlnt have the slightest idea.
All throughout uni we are taught methods of making our provided education interesting so it is more appealing to the variance in student type in the
class....
So what about the kids who are interested but are hands on learners? the simple mundane pracs just dont cut it for them, they need explicit
demonstrations, they need to get in there and do it, explore each aspect.
Are you leaving them behind? restricting them from an education just because you dont want to put in the minute amount of effort it takes to make a
topic interesting and exciting? Nice teacher you would make....
Me? I make every class, pracs or book work as exciting as i can, that way when my students come to the test they can remember the cool things i did to
help them remember it inrstead of going "oh yeh that was that boring day in science...."
Remember, teachers are far more than educators, we dont just shovel information out to you.... thats what a LECTURER does... teachers do far far more.

You misunderstood me. If a student can't boil water without getting third degree burns then the teacher shouldn't be held responsable.
I'm not saying we shouldn't have hazardous demonstrations. I'm saying that the teacher's first responsability is to his or her
classes safety. You can do dangerous reactions safely, and it doesnt have to be dangerous to be interesting. But again, the teacher isnt there to
entertain you, the teacher is there to make you understand. If you want to do a dangerous or more interesting or different reaction the
teacher should be able to help you do it safely without the whole class destracting him/her. Sure, everyone likes interesting stuff, but you
shouldn't put people at risk just to make their lives more interesting.
My chemistry labs were interesting enough, and hands on enough (And I am a hands on learner) that I know enough to start doing chemistry as a hobby,
which is much more interesting. I am glad that I took chemistry and I would be even if the labs were boring because now I can do what I want to do.
The chemistry labs are usually (At least where I am) open to the students who don't have axcess to chemicals or labware. I don't know about
safety regulations but when I took my labs I didn't notice any irrational safety precautions.
This is just what I think from what I have seen, I'm not trying to insult anyone. If you think what I'm saying is wrong then I will
be happy to debate it.

I live across the pond, so my outlook might be a bit different.
Here
http://www.hmso.gov.uk/acts/acts1988/Ukpga_19880052_en_1.htm
is a copy of the legistlation that forbids me driving while drunk. Its the real legislation on the government's website.
Can someone find me a similar piece of law that would forbid me doing, for example, the thermite reaction, as a classroom experiment?
UK or USA law would do me as an example.
If not, then you can't blame the safety regulations and the answer to the question is "no".

There is no law about these things per se, but you still can't do them. I believe that they are prohibited by the people lower down in the chain:
principals, superintendents, etc. The way these things seem to work is that an existing law, say "no killing students", is interpreted to
mean, "no (pseudo)dangerous materials anywhere near schools". The laws are what we interpret them as.
I’ll admit I know little about this level of bureaucracy, so feel free to correct my theory.

Chemistry
Neutrino, it's true that the people above the teachers are primarily responsible for the
limited use of chemicals. They're worried about getting sued by lawyers.
Magpie, you mentioned a "virtual" chem lab. I'm glad I had a "hands on" chem teacher
in high school. I count myself among the lucky ones. Virtual labs won't cut it - especially
for a pyro like me.

this should represent US, HS education with reg's. 2nd ed and uni's run a little different.
I think your looking at this the wrong way... there are these organizations which prohibit a lot of chemicals or materials from going into schools or
in general, entities over a certain size. OSHA regulations is in place for teachers (they are workers) OSHA regulations in place for the public
(students) in these 'work places'. there are DNR rules which prohibit the generation of certain Haz Waste etc. There is another organization
which regulates materials safety, but I cant remember its name. And of course public schools MUST follow these rules since they are bodies of the
State. Private schools, which are ussualy smaller in size get a little more freedoms, but most of the freedoms come from the local side. There are
also Supt. rules (since they would ultimatly be concerned with student safety(and money haha), Principal rules, budget rules (most people do not
realize schools must put money into certain accounts, and only money from the asigned accounts can be used on the things they are asigned to. (so
people bitch when there is money to put carpet into the office area's, but the chemistry labs don't have heating plates or something.) But
its the dumb way that works. (the only way around that, is to get someone smart on school boards, but that never seems to happen)
Then there are teacher rules... there are some things teacher just don't want to do for safety or whatever. There are also limitations on
ventalation (back to OSHA). If you want to throw a penny into HNO3 to show students something interesting, you need a place for the NO2 to go, and it
needs to be somewhere which will filter the haz waste (back to DNR). The biggest sticker though isnt the rules. Its the fricken budget I mentioned.
Its a tricky issue since it costs money to buy chemicals, ship chemicals(sometimes it costs as much to ship the crap as the actual chemical), store
the chemicals and if you let the chemicals expire, you have to PAY to get rid of them correctly (DNR and OSHA again). Have you ever gone to www.fishersci.com? there are other chemicals suppliers too, but regardless, this stuffs expensive considering you need to put money into other
things in the science budget.
Yes, I agree however, that it is very difficult for science teachers to find demo's and activities which capture the attention of students AND
allow them to draw correlations in science. from the education standards, the teacher needs to teach how to observe relevent data and make
speculations. This can be done on paper. but... err..this is not very interesting to people who are trying to learn science esp chemistry or physics
(which is initialy difficult to teach). So demos , labs and hands on are great, only the students also need to be safe in the realms of common sense.
*skipping common sense with safety arguments*
Overall, I vote no. I personaly feel that safety is not enforced enough. The ones who are really interested (and smart) find ways to be safe and get
around regulations.
I suspect that there may be dumb rules which make extreme cases for this question, but can you list some examples of things which regulations ban? (be
location specific)

So for those of us who wouldn't have looked twice at chemistry because its all numbers and stoichometric ratios and avogadro's numbers and
moles and dry and boring should not be allowed to enjoy chemistry? I had one class like that and it was my first one. I dreaded taking the next
years class. More numbers and such I thought. Thank $Diety that I had a different teacher who thought to give examples, and have us help and do
experiments and hands on equipment. From that class alone there were at least 10 converts.
And Disregarding getting new people interested. Why should the interested ones have to do it at home? Its safer in the lab is it not?
The only reason there is a budget problem is that if elsewhere is anything like my school, 99% of the budget went towards our loosing sports teams.
Education no longer matters just the sports.

I think it is safer doing chemistry at home; it just happens that often what people do at home is very dangerous! At my house I at least have
good gloves, a face shield and goggles and soon a good gas mask. I also don't have to deal with dumbasses that can't record data and slow me
down(god damn I had to deal with so much stupidity last year)
As too learning chemistry work put into it is what you get out of it. Sure learning such detail about orbitals and sigma bonds is hard work - makes
stoich look like a piece of cake. But that beautiful, perfect control over matter is so there! I know Im getting closer every day. Closer to
that understanding in my mind giving me absolute power. Make any drug, synth any poison, produce any color, destroy anything and create everything.
Chemistry is the central science and every hardship is worth it. To have that level of control is intoxicating. Read Perfume by
Suskind and change perfume to chemicals, odor to organic and smell to science. Don't think Im going to try to distill any virgins however
What if, what is isn\'t true?

I had a look at the articles.
Do you mind if I smile rather than weep?
Here in the UK, and generally across Europe, there is a problem with pensions. Basicly, too many people are living long after 60 (or 65) and drawing
cash from the pension funds.
There are a number of possible solutions to this but one is "making" peole stay on at work after 60. The UK Govt and the unions
reperesenting the public sector workforce are currenly sorting out rules to permit flexibillity in this matter. (Letting those who wish to quit at 60,
but permitting people to stay on at work as long as they can.)
I'm pretty sure the other European govenments are doing the same sort of thing. The last thing the Government wants people to do is retire at 60.
There is every chance that, when I come to retirement, it will be at 65 rather than 60- they may have to raise the bar even further as healthcare
costs rise.
Not only that, but sacking someone for turning 60 would be a breach of the European Human rights act.
This is another case of "OH My God, Look At the Crazy Laws!" where the laws, like those forbidding experiments in high school labs, simply
don't exist.
This begs the question, who starts this sort of story and why?

Benzyl chloride and allyl chloride are industrial chemicals with full safety advice. Benzyl bromide, benzyl iodide, allyl bromide and allyl iodide are
not and do not have the same info. As a chemist I would expect the bromide and iodide to be more toxic. Work with the devil you know and just because
there is not a piece of paper use common sense.

Here in the UK my old man in his 80,s is suprised at all the benefits. Free bus pass, free TV licence, cheap road tax and insurance, help with winter
heating and post-help with burying his wife.

Allyl chloride is rather volatile and a pain in the neck to work with.
On the other hand, is it in any sense relevant to this thread?

It is sadly predictable that the majority feel that education is being hampered by regulations that don't really exist.
It would be funny if they were to think that the tooth fairy was harming education, but this is a tragedy.

The regulations may not always exist on paper, but they certainly do exist in the minds of people who ‘would’ be affected by them, i.e. the
teachers and superintendents. The rules don’t have to be formal to apply. Sadly, a general sense of restraint in the minds of the teachers will be
more than enough.

I think that "safety regulation" in this thread should be interpreted as restraint exercised by politicians, local authorities, lobby groups
(parents, econuts) and people who are otherwise in a position to influence chemical education on a highschool level.
There may not be explicit laws, but if a teacher can get sued under some other law for something minor, this still has considerable effect. This is
mainly caused by the idiotic interpretation of liability these days.

Actually, I conceived the poll in that regulations may be hampering chemical education as a whole, not just high school.
unionised, looking back at your first post in this thread, yes, I would agree that it is not explicitly stated in the applicable laws that
such-and-such reaction should not be done as a classroom demonstration. It is to my knowledge, however, that "unwritten rules" guised as
safety regulations have done more than their fair share of curtailing activities seen to be valuable in illuminating chemical concepts to the
uninitiated. That, and the fear of litigation, as vulture mentions.

Perhaps we need a new poll, "Is education in chemistry being ruined by ambulance-chasing lawyers (Y/N)"
The problem isn't regulations, it's the lack of understanding of risk by parents, headteachers and whoever. Those who wish to pretend that
terrorism and/or drug manufacture is a major threat to our day to day lives also feed into this problem. Again, if the people knew how to evaluate
real risk, they wouldn't let governments ban the sale of nitrate fertilisers.

In high school chemistry, most of the reactions that would be regulated are probably out of the courses' scope. As for mercury thermometers;
they are a necessity. If the gov't bans mercury thermometers due to health concerns, why dont they ban partially hydrogented or brominated oils
from the cafeteria?

There are still many interesting ones that are within the scope of high school chem that aren't done, e.g. alkali metal + water.
What's so necessary about mercury thermometers? What about alcohol?

No (to a first approximation). I think it's more a result of the changing role of chemical education. Back in the day, if you were taking
cemistry courses there was a decent chance you would become a chemist, or at least someone who might need to work in a lab environment. If you were to
ask a lower level college chemistry class today what their carreer goals are, chances are good that you won't get a single person wanting to be a
chemist. It's simply not worth the risk for people that won't need the experience.
This is not to discount fear of litigation, of course. Yesterday, for example, there was an advertisement on TV trolling for people with benzene
exposure.

In reference to nitrate fertilizers I read today that the Simplot Fertilizer company (USA) is planning to stop production of ammonium nitrate.
Reasons given were: 1) wanting to not allow terrorists to get a hold of it, and 2) don't want the hassle of complying with government regulations
that are being proposed in congress. Agrium, a Canadian competitor, however, said that they have no plans to stop production. Simplot production is
currently 40,000 tons/yr.

"...what's so necessary about mercury thermometers? What about alcohol?"
If you're going to be taking the temperature of something that would boil alcohol at its current condition, it really isn't a good idea to
use an alcohol thermometer for it. But this is still a moot point in defending
mercury thermometers; gallium themometers (although a bit expensive) and thermocouples are good alternatives to using mercury.
tetrachloromethane (whew! long name ), they won't ban partially hydrogenated
oils since there are usually no cheaper alternatives.
Geomancer, was it a law firm?

Who hasn't been "exposed" to benzene? Everytime someone fills a car with petrol/gasoline, they're handling of the order a litre
of benzene. Petrol/gasoline is only available to the public because it's a necessity with no economic alternative. If it wasn't required
as a fuel, it would have been banned years ago.

When the hell did political oreitation or whatever the hell you call it combine with science to form terrorism and anarchy. Science is science and a
fucktard with a bomb wanting to cause a "revolution" is some fucktard on the internet. In other words when you go up to somebody and say Im
going to cook my food with propane they dont go OMG CALL HOMELAND SECURITY THIS GUYS GONNA MAKE AN FAE LOLOL
Until people get a clue and realize that science HAS ABSO FUCKING LUTLY nothing to do political views we will contiune to have this nonsense
regulations...
